	This section describes how to start and quit an IRIS session, and how to
customise some of the IRIS configuration options.

The most common way of starting an IRIS session (after you have
installed the IRIS files on your disk) is to run the following line in
the Matlab command window:

\begin{verbatim}
addpath C:\IRIS_Tbx; irisstartup();
\end{verbatim}

The first command, \texttt{addpath}, adds the IRIS root folder to the
Matlab search path. The second command, \texttt{irisstartup},
initialises IRIS and puts the other necessary IRIS subfolders, classes,
and internal packages on the search path. \emph{Never} add these other
subfolders, classes and packages to the search path by yourself.
